Migraine aura is a neurological phenomenon affecting ~30% of migraine patients — temporary neurological symptoms that precede or accompany headache. Aura includes visual disturbances (scintillating scotoma, zigzag lines), sensory changes (numbness, tingling) and language problems (difficulty speaking). Understanding aura helps distinguish migraine from other conditions.
What is migraine aura
Prevalence: affects ~30% of migraine patients — not all migraine has aura. Timing: typically precedes headache by 5–60 minutes — but can occur during or after. Duration: usually 5–60 minutes — temporary symptoms. Mechanism: cortical spreading depression — wave of brain activity. Types: visual aura (most common), sensory aura, language aura, motor aura (rare). Reversible: aura symptoms resolve completely — temporary neurological dysfunction.
Visual aura symptoms
Scintillating scotoma: flickering lights or spots — most common visual aura. Zigzag lines: fortification spectra — jagged lines expanding across vision. Blind spots: scotoma — area of vision loss. Color changes: colors may appear altered — visual distortion. Movement illusions: objects may appear to move — visual misperception. Tunnel vision: peripheral vision loss — expanding blind spot. Duration: typically 10–30 minutes — resolves completely.
Sensory aura symptoms
Numbness: tingling or numbness starting in hand/fingers — spreads up arm. Pins and needles: paresthesia — unusual sensations. Weakness: motor aura — rare, suggests hemiplegic migraine. Spread: symptoms spread gradually — follows cortical spreading depression. Duration: typically 10–30 minutes — resolves completely. Location: usually one side of body — but can be bilateral.
Language aura symptoms
Aphasia: difficulty finding words — most common language aura. Dysarthria: slurred speech — motor component. Reading difficulty: trouble reading — visual processing affected. Writing difficulty: trouble writing — motor planning affected. Duration: typically 5–30 minutes — resolves completely. Rare: language aura is less common than visual or sensory — but well-documented.
When aura needs medical evaluation
If you have new aura symptoms, aura lasting >60 minutes, motor weakness, or aura without headache — see a neurologist immediately. Aura can mimic stroke — proper evaluation is essential.
